WILLARD A. PE'ITEYS, OF" WILGOX, NEBRASKA.

GRAIN CLEANER, SEPARATOR, AND DRIER.

To all whom it may concern:

Be it known that I, WILLARD A. Pn'r'rnYs, a citizen of the UnitedStates, residing at lVilcox, in the county of Kearney and State ofNebraska, have invented certain new and useful Improvements in GrainCleaners, Separators and Driers, of which the follow ing is aspecification. f This invention has for its object to provide .anapparatus for the treatment of grain including a novel type of, hoodprovided with a series of internal baffles over which the grain iscaused to travel and which is -which the foreign matter is separatedfrom the grain and conducted to a separate discharge spout in thereceiving hopper.

With the above and other ob ects 1n view,

. as will appear as the description proceeds,

the invention comprises the various novel features of construction andarrangement of parts which will be more fully described herein and set.forth with particularity in the claims appended hereto.

Reference is had to the accompanying drawings forming a part of thisapplication, in which like reference characters indicate thecorrespondin parts throughout the several views, in whic Figure 1represents a front elevation, partly in section and partly broken awayof the improved cleaning, separating and drying device,

Fig. 2 represents a perspective view of the receiving hopper detached, V

Fig. 3 represents a vertical sectional view through the ventilatinghood, and

Fig.4- represents a vertical sectional view through the receivinghopper.

Referring to the drawings in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates generally the ventilating hood which consists essentially offront and rear walls 6 and a top 7 having a hinged section 8facilitating access-to the interior of the'hood. The sides of the hoodare open and thefront and rear walls are maintained in spaced relationby bolts Specification of Letters Patent. Patented J 11g 29 192()Application filed May 3, 1919.

9 to which the pulley supports -10, to be hereinafter more fullydescribed, are attached.

The upper portion of the rear wall of the hood is formed with an inletopening 11 through whichgrain is introduced into the interiorof the hoodand a series of inclined and staggered bafile plates 12 is arrangedbeneath the opening 11 andis designed to cause the grain to pursue acircuitous course through the hood.

Aseries of hinge rods 13 is secured'to the opposed edges of the frontand rear walls and pivotally support groups of ventilating shutters 14.The shutters',,when closed, lie in overlapping relation, as clearlyshown in Fig. 3, to prevent the entrance of water intofthe hood and, asthe bafiles 12 are arranged in spaced relation air is permitted tocirculate through the hood to accelerate drying of the grain flowingtherethrough.

A pair of pulleys 15 is supported at the outer terminals of the supports10 and cables 16 are arranged thereover.

The front terminals of the several hinge rods 13 are directed angularlyas at 17 and the angular terminals of each group of ventilating shuttersare arranged in parallel relation and are connected by a rod 18 wherebythe several shutters are caused to move in synchronism. One of the hingerods of each group is also extended rearwardly of the hood 5 and isdirected angularly and connected with one of the cables 16for'convenience in adjusting the shutters to control the passage of airthrough the hood.

The lower open discharge end 20 of the hood is supported upon andcommunicates with an inclined chute 21 the lower terminal of which issupported upon the receiving hopper 22 and-a separator screen 23 isarranged within the chute 21 above the inclined bottom thereof andextends upwardly beneath the discharge opening in the hood wherebythegrain discharged therefrom is deposited upon the screen and moveddownwardly thereon by gravity.

The receiving hopper 22 is provided with a vertical internal partition23 dividing the interior of the hopper into the chambers 24 and 25. Thelower edge of the separator screen 23 is extended over the top edge ofthe partition 23" whereby the clean grain is directed into the chamber24 and is conducted therefrom through a laterally projecting dischargespout 26. The dirt and other foreign matter which falls through theseparator screen 23 and moves down-- wardly upon the inclined bottom ofthe chute 21 is deposited in-the chambers and is conducted therefromthrough the discharge spout 27. 7

What I claim is:

1. In a device of the character described, a receiving hood having areceiving opening therein, a plurality of inclined and staggeredlyarranged bafi'les arranged in the v hood beneath the opening therein,hinge tilating shutters hingedly rods arranged in the hood groups ofvensupported upon the rods in the opposite sides of the hood to controlthe passage of air therethrough, one

hinge rod at each group being extended and directed angularly, operatingmeans connected with the angular terminals of the rods, and meansconnecting the opposite ends of the rods of each group wherebysimultaneous adjustment of the several shutters of each group isaffected.

2. In a device of the character described,

' a hood provided with ventilating openings,

hinge rods arranged transversely of the openings, opposed groups ofshutters pivotally supported upon said rods and nor mally retained inclosed position by gravity, one rod of each group being directedangularly, a flexible operating element having its terminals connectedwith the angular terminals of said rods, the opposite terminals of therods of each group being directed op positely to, the first mentionedangular terminal, and means connecting the last mentioned angularterminals of the several rods of each group whereby the shutters of suchgroup are simultaneously adjusted.

3. Ina device of the character described, a hood including front andrear Walls and provided with open sides and bottom, one

of said sides having a receiving opening in the upper portion thereof,hinge rods extending between'and maintaining the-front and rear walls inspaced parallel relation, and opposed groups of shutters carried by therods and adapted, when closed, to lie in overlapping relation to formclosures for the open sides of the hood. c

In testimony whereof, I afiix my signature hereto.

WILLARD PETTEYS.
